Question

我开始在Laravel 5.4提供的Slack上使用通知系统，它太棒了（src：https://laravel.com/docs/5.4/notifications）！

但是我有一个问题是通过队列通知它会触发异常：序列化＆＃39;关闭＆＃39;不允许在/var/www/project_test/vendor/laravel/framework/src/Illuminate/Queue/Queue.php:125

你能帮帮我吗，我的错误是什么？

信息：

在没有Queue
队列驱动程序是数据库
队列工作程序以＆＃39; queue：work --queue = default，mail --sleep = 3 --tries = 3 --timeout = 60＆＃39;

这是我在app / Notifications / Slack.php中的代码：

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\SlackMessage;

class Slack extends Notification implements ShouldQueue
{
    use Queueable;

    private $channel;
    private $username;
    private $icon;
    private $message;
    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct(String $channel = '', String $username = '', String $icon = '', String $message = '')
    {
        $this->channel = $channel;
        $this->username = $username;
        $this->icon = $icon;
        $this->message = $message;
    }
    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['slack'];
    }
    /**
    * Get the Slack representation of the notification.
    *
    * @param  mixed  $notifiable
    * @return SlackMessage
    */
    public function toSlack($notifiable)
    {
        return (new SlackMessage)
                ->from($this->username, $this->icon)
                ->to($this->channel)
                ->content($this->message);
    }
    /**
    * Get the array representation of the notification.
    *
    * @param  mixed  $notifiable
    * @return array
    */
    public function toArray($notifiable)
    {
        return [
            'channel' => $this->channel,
            'username' => $this->username,
            'icon' => $this->icon,
            'message' => $this->message,
        ];
    }
}

这是我在app / Providers / AppServiceProvider.php中使用松弛通知的代码：

namespace App\Providers;
use Queue;
use Carbon\Carbon;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\Facades\Log;
use Illuminate\Queue\Events\JobFailed;
use Illuminate\Notifications\Notifiable;
use App\Notifications\Slack;

class AppServiceProvider extends ServiceProvider
{
    use Notifiable;
    /**
     * Route notifications for the Slack channel.
     *
     * @return string
     */
    public function routeNotificationForSlack()
    {
        return 'http://hook.slack.com/XXXXXx/my_slack_endpoint';
    }
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        // When a queue job fail
        Queue::failing(function (JobFailed $event) {
            // Notify team of failing job
            $when = Carbon::now()->addSeconds(10);
            $this->notify((new Slack('slack_channel', 'slack_username', 'slack_icon', 'Job Failed !'))->delay($when));
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

Answer 1

像themsaid这样的Loook在laravel bug tracker上回答了您的问题请求。为了节省其他人的点击，如果你不介意，我会在这里引用这个回复：

不要使用Illuminate \ Notifications \ Notifiable，它的意思是   与Eloquent模型一起使用，现在Queue驱动程序将尝试进行serliaize   你的服务提供商认为这是通知，这是事情   你不想要。

相反，您可以创建一个MySlack类或使用的东西   需要通知并且您从服务提供商处发送通知   像：

Notification::Send(new MySlack(), new MyNotification());

Answer 2

确保已实现ShouldQueue并使用Queueable特性：

class MyNotification extends Notification implements ShouldQueue{
    use Queueable;

    // ...
}

Laravel 5.4上的通知不可用（SlackMessage）
